## Wish for quiet toys

About a month ago we picked up at work a SuperMicro X9SCM-F in a 4U rackable case; we didn’t know who the case maker was until @thegpfury noticed it was a Norco case.

This is all well and good but we had a major problem for usage: The noise! This being enterprise hardware no consideration was made for acoustics since the device would live in a datacenter but in my case we want to use it at home.

This is what it sounds with all the fans on (NBM-MAT case fans, the lot of them):

Super loud. Like a 70s VW Bug that has had zero maintenance.

So then I tried with only the fans in the back:

And finally with only the CPU fan

At this point it was clear all the fans were buggered to hell. With them all being 80x80x25 it turned out Noctua do have great replacements available; for the backplane I got NF-R8 redux-1200 and for the read I got the NF-R8 redux-1800 PWM so the motherboard can control the speed on them. The power supply is still fully functional and with it being a Corsair AX760 we know we don’t have to worry about the noise coming from it.

This is how it sounds with two backplane fans and both back fans installed:

Much, much better! So quiet very stealth!!!

For the time being it should be okay to run it with just these fans; the apartment is kind of cold and the additional cooling will not be needed until the summer, by which point the thing will probably get upgraded storage. If only more manufacturers had in consideration the acoustics of their devices; there’s an HP ProLiant DL160 G6 laying around that is also loud as fuck but there’s no clear path to making it quieter; I know 1U devices don’t have the most space but even 2U devices are still loud as hell when they can be much improved.

Perhaps a 2U system with quiet fans and good gaming hardware, mounted under a desk top. That’d be nice. Like a Lack rack but for actual desk use. That’d be nice.

Turning it on with all the fans installed at the factory. It’s loud.

## I want a drink and it’s not even 0700 yet

On this here blog I use a few things to help secure everything down and avoid issues, namely, nginx location blocks disallowing access to resources, fail2ban tracking nginx logs to prevent people hammering server or trying to do improper things, and the “Limit Login Attempts” WP plugin.

A combination of all these broke access with the wordpress mobile app. Ended up having to disable the wordpress fail2ban jail and altering some of the nginx directives.

This is going to be a pain in the ass to debug cos the wordpress app doesn’t have any kind of proper error messaging, urgh.
